MULTIPLE CHOICE

Circle the choice that best completes the statement or answers the question. 1) The Pentagon building in Washington, D.C., 2) During each marking period, there are five is shaped like a regular pentagon. If the length tests. If Vanita needs a 65 average to pass of one side of the Pentagon is represented by this marking period and her first four grades n + 2, its perimeter would be represented by are 60, 72, 55, and 80, what is the lowest score she can earn on the last test to have a a) 5n + 10 passing average? b) 5n + 2 a) 58 c) n + 10 b) 65 d) 10n c) 80 d) 100

3) The lengths of the sides of home plate in a 4) Solve: 43a + 10 – 26a = 27 baseball field are represented by the expressions in the accompanying figure.

Which expression represents the perimeter of a) a = - 17 the figure? b) a = - 1 a) 5xyz c) a = 1 2  3 b) x y z d) a = 17

c) 2x 3yz

d) 2x 2y  yz

5) Solve: –6m – 6 + 8m = -5 + 2m – 1. 6) If 4x = 32, find the value of 35 – 5x. How many solutions are there to the equation?

a) Two solutions a) -5 b) Infinitely many solutions b) - 3 c) No solutions c) 3 d) Only one solution d) 5 EXTENDED RESPONSE: SHOW ALL WORK in the space provided. 7) A video store charges a monthly membership fee of $7.50, but the charge to rent each movie is only $1.00 per movie. Another store has no membership fee, but it costs $2.50 to rent each movie. How many movies need to be rented each month for the total fees to be the same from either company? (Define your variables, write and solve…)

8) Stan has exactly $2.00 in nickels, dimes and quarters. He has 4 more dimes than quarters. The number of nickels he has is 2 more than three times the number of quarters. Define your variables, then write and solve an equation to find how many nickels, dimes and quarters Steve has.

9) Find 2 consecutive odd integers such that three more than three times the first is three less than three times the second. 10) Solve: -2(x – 5) + 4x = 18 1 11) Solve: 6a - (8a + 12) = 18 2

12) Solve: x + 4 – 6x = 6 – 5x - 2 13) Solve: 6(x + 7) – 20 = 6x

1 14) (6h + 3) – 4h + 2 = -2(h – 3) + 3h 3
